... et al., 2015a , b ) and beaked whales ( Martín López et al., 2015 ), switch between gliding, continuous stroking and burst-and-glide gaits throughout a dive. In the present study, we found that such gait changes modify the energetic cost of stroking and of a dive. For the odontocetes examined...

...-diving cetaceans dive within their ADLs. Beaked whales (including Ziphius cavirostris and Mesoplodon densirostris ) routinely perform the deepest and longest average dives of any air-breathing vertebrate, and short-finned pilot whales ( Globicephala macrorhynchus ) perform high-speed sprints at depth. We...

...M. Johnson; P. T. Madsen; W. M. X. Zimmer; N. Aguilar de Soto; P. L. Tyack SUMMARY Blainville's beaked whales ( Mesoplodon densirostris Blainville)echolocate for prey during deep foraging dives. Here we use acoustic tags to demonstrate that these whales, in contrast to other toothed whales studied...

...Peter L. Tyack; Mark Johnson; Natacha Aguilar Soto; Albert Sturlese; Peter T. Madsen SUMMARY Sound-and-orientation recording tags (DTAGs) were used to study 10 beaked whales of two poorly known species, Ziphius cavirostris (Zc) and Mesoplodon densirostris (Md). Acoustic behaviour in the deep...

...P. T. Madsen; M. Johnson; N. Aguilar de Soto; W. M. X. Zimmer; P. Tyack SUMMARY Toothed whales ( Cetacea, odontoceti ) emit sound pulses to probe their surroundings by active echolocation. Non-invasive, acoustic Dtags were placed on deep-diving Blainville's beaked whales ( Mesoplodon densirostris...
